small bathroom, and not enough hot water or heat. Generous contributors J. Josiah and Thomas J. Emery came to the rescue. They donated land in Mt. Auburn and built a three-story brick hospital. On November 23, 1887, all patients were transferred from the Walnut Hills location to the new hospital on Mason Street, near The Christ Hospital. Originally endowed with a fund of $3,506.48 in November 1884, the hospital's endowment had grown to over $85,000 by the turn of the 20th century. In 1904, a new three-story wing, connecting with the rear of the main building, was built. The addition cost over $20,000 at the time, and included provisions for a large play-room, a chapel and an isolation ward for children with contagious diseases. A new operating room was installed on the top floor of the main hospital at this time, and various other improvements increased the capacity of the hospital at this time to 90 beds. The 1920s brought dramatic changes while under the leadership of William Cooper Procter, president of the board of trustees, and Albert Graeme Mitchell, MD, chair of the Department of Pediatrics at the University of Cincinnati College of Medicine and physician-in-chief of The Children's Hospital. In 1926, the hospital moved to a new 200-bed facility near the College of Medicine and established an academic affiliation with the college. In 1928, William Cooper Procter donated $2.5 million to build and endow The Children's Hospital Research Foundation, which opened in 1931. The hospital entered the decade of the 1930s as an important center for pediatric patient care, education and research—as it continues to be today. The hospital has been involved in a variety of medical breakthroughs, most prominently Dr. Albert Sabin's development of the oral polio vaccine, which went into use in the United States in 1960.
